The Hobbit is making film fans feel queasy due to its dizzying and double-speed 3D technology, it has been revealed.
The adventures of Bilbo Baggins and co have been shot at twice the speed of older movies with a dazzling 48 frames per second.
Some viewers claim it is bad for their elf.
Fans have likened watching the Peter Jackson blockbuster to taking a rollercoaster ride with one warning "This is not for wimps."
The film, the first of a trilogy set before the events in the hit 'Lord of the Rings' series, is out next week but audiences at the New Zealand premiere have posted their views online.
"I left loving the movie but feeling sick," the Mirror quoted one fan as tweeting.
"My eyes cannot take everything in, it's dizzying. Now I have a migraine," another tweeted.
However, the self-confessed "avid Middle Earth fan" added "Can't wait to see it again."
Film critics who were shown early versions of the movie, starring 'The Office' actor Martin Freeman as JRR Tolkien's hobbit Bilbo, had spoken out about how the upgraded technology left audiences feeling unwell.
"Watch it for very long and you will end up with crossed eyes," technical writer Devin Faraci said, while American critic Peter Sciretta said the effect was "jarring".
